Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and in particular to a vacuum cleaner connection module and a vacuum cleaner. Background Technology

[0002] Vacuum cleaners are common cleaning devices. A vacuum cleaner includes a floor brush module and a handle module housing a motor. When the vacuum cleaner is working, the floor brush assembly is placed on the ground to absorb dust, hair, etc. The dust, hair, and other particles sucked in by the floor brush assembly are then carried by the airflow into the handle module for collection. In some vacuum cleaners, the floor brush module and the handle module can rotate relative to each other for easier user operation and storage. To allow the floor brush module and handle module to rotate relative to each other, the conventional implementation uses a flexible hose connecting the floor brush module and the handle module. This flexible hose can deform to allow the floor brush module and handle module to rotate relative to each other.

[0003] When using a vacuum cleaner, the floor brush assembly may clog the hose when it sucks in a large amount of hair, affecting the normal operation of the vacuum cleaner. Current methods of connecting the hose and floor brush module include interference fits and threaded connections, which prevent quick disassembly. Each time hair or other sucked-in material needs to be cleaned from the hose, a rather cumbersome and complicated process is required to separate the hose from the floor brush module, impacting the user experience.

[0024] Furthermore, when the first connecting part is sleeved on the second connecting part, the second snap-fit ​​groove is an annular groove, and the thickness of the second snap-fit ​​groove is adapted to the thickness of the snap-fit ​​part. The snap-fit ​​part is snapped into the second snap-fit ​​groove and can slide within the second snap-fit ​​groove. The shape of the first snap-fit ​​groove is adapted to the shape of the snap-fit ​​part, and the snap-fit ​​part is relatively fixed to the first connecting part.

[0051] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0052] like Figures 1 to 7 As shown, a vacuum cleaner connection module corresponding to a preferred embodiment of the present invention includes a floor brush assembly 1, a flexible connecting tube 2, and a connecting sleeve 3 for connecting the floor brush assembly 1 and the flexible connecting tube 2.

[0053] Further reference Figure 1 and Figure 5The floor brush assembly 1 includes a floor brush body 100 and a connector module 200. The floor brush body 100 includes a floor brush housing 14 and a floor brush 17 installed inside the floor brush housing 14. A suction port adjacent to the floor brush 17 is provided at the bottom of the floor brush housing 14. The floor brush 17 scrapes up dust, hair, and other debris on the floor so that the dust, hair, and other debris can be sucked into the floor brush assembly 1 through the suction port. The floor brush assembly 1 also includes a suction channel 11. The connector module 200 includes a first connecting part 12. The floor brush body 100, the flexible connecting tube 2, and the connector module 200 are sequentially connected to form the suction channel 11. The suction channel 11 communicates with the suction port so that the dust, hair, and other suction objects sucked in by the floor brush body 100 move from the suction port toward the flexible connecting tube 2. To facilitate the movement of the floor brush assembly 1, the floor brush assembly 1 may also be provided with a roller assembly. Specifically, the floor brush body 100 may include a rear wheel assembly 15 located at the rear and a front wheel assembly 16 located at the front. When in use, the rear wheel assembly 15 of the floor brush assembly 1 is close to the user.

[0054] Further reference Figure 1 The flexible connecting pipe 2 includes a hose body 23, a second connecting portion 21 disposed at one end of the hose body 23, and a third connecting portion 22 disposed at the other end of the hose body 23. For example, the flexible connecting pipe 2 includes a hose body 23 and an upper hose connector 25 and a lower hose connector 26 connected to the hose body 23. The hose body 23 is a hose made of a flexible material. One end of the hose body 23 is connected to the upper hose connector 25, and the upper hose connector 25 is provided with the second connecting portion 21, which connects to the first connecting portion 12. The other end of the hose body 23 is connected to the lower hose connector 26, and the lower hose connector 26 is provided with the third connecting portion 22. The upper hose connector 25 and the lower hose connector 26 can be rigid structures with high hardness, so that the second connecting portion 21 formed on the upper hose connector 25 and the third connecting portion 22 formed on the lower hose connector 26 can be stably connected to other components. The upper connector 25 and the lower connector 26 of the hose can be made of plastic, and the upper connector 25 and the lower connector 26 can be threaded to the hose body 23 respectively.

[0055] Further reference Figures 2 to 4 The connecting sleeve 3 is connected to the first connecting part 12 and the second connecting part 21, so that the flexible connecting tube 2 can be installed on the floor brush assembly 1. The connecting sleeve 3 is provided with a snap-fit ​​part 31 and a trigger unit 32. The snap-fit ​​part 31 can snap with the first connecting part 12 and the second connecting part 21 to restrict the relative movement of the first connecting part 12 and the second connecting part 21 along the direction of suction flow, thereby realizing the connection between the flexible connecting tube 2 and the floor brush assembly 1. At this time, the flexible connecting tube 2 and the dust suction channel 11 of the floor brush assembly 1 are connected and form a stable flow channel, in which dust, hair and other suction materials can flow.

[0056] The first connecting part 12 may be sleeved on the second connecting part 21, or the second connecting part 21 may be sleeved on the first connecting part 12. The first connecting part 12 and the second connecting part 21 partially overlap; the connecting sleeve 3 is installed at the overlapping position of the first connecting part 12 and the second connecting part 21 to restrict the relative movement of the first connecting part 12 and the second connecting part 21 along the direction of the inhaled material flow.

[0057] The trigger unit 32 is directly or indirectly connected to the latching part 31. The trigger unit 32 can be pressed to move, and when the trigger unit 32 is pressed, it drives the latching part 31 to expand outward. At this time, the latching part 31 gradually separates from the first connecting part 12 and / or the second connecting part 21, thereby releasing the relative movement restriction of the latching part 31 on the first connecting part 12 and the second connecting part 21. The flexible connecting tube 2 can then be separated from the floor brush assembly 1. At this time, the end of the flexible connecting tube 2 is exposed to the outside of the floor brush assembly 1, and the user can clean the internal space of the flexible connecting tube 2. Specifically, the latching part 31 can be separated from both the first connecting part 12 and the second connecting part 21 under the drive of the trigger unit 32 to release the relative movement restriction between the first connecting part 12 and the second connecting part 21. Alternatively, the latching part 31 can be separated from only one of the first connecting part 12 and the second connecting part 21, so that one of the two connecting parts can be separated from the latching part 31, thereby releasing the relative movement restriction between the first connecting part 12 and the second connecting part 21.

[0058] By providing a connecting sleeve 3 with a locking part 31 and a trigger unit 32, the locking part 31 restricts the relative movement between the first connecting part 12 and the second connecting part 21, thereby connecting the flexible connecting tube 2 to the floor brush assembly 1. The trigger unit 32 releases the relative movement restriction imposed on the first connecting part 12 and the second connecting part 21 by the locking part 31 under pressure. Therefore, the user only needs to press the trigger unit 32 to separate the first connecting part 12 and the second connecting part 21, thus separating the flexible connecting tube 2 from the floor brush assembly 1. The operation of separating the flexible connecting tube 2 and the floor brush assembly 1 is relatively convenient, enabling quick disassembly of the flexible connecting tube 2 and the floor brush assembly 1.

[0059] In some specific embodiments, after the snap-fit ​​portion 31 is connected to the first connecting portion 12 and the second connecting portion 21, a sealing element 24 may be provided between the first connecting portion 12 and the second connecting portion 21 to improve the sealing performance between them. The sealing element 24 may be a sealing ring, and it abuts against the first connecting portion 12 and the second connecting portion 21 respectively to achieve a seal between them.

[0060] Since the snap-fit ​​portion 31 engages with the first connecting portion 12 and the second connecting portion 21, there may be gaps at the engagement point, potentially leading to air leakage. Therefore, the seal 24 needs to prevent gas from flowing towards the snap-fit ​​portion 31. Specifically, further refer to... Figure 7 When the first connecting part 12 is fitted onto the second connecting part 21, the sealing member 24 is located upstream of the first snap-fit ​​groove 121 along the direction of the suction flow, while the snap-fit ​​part 31 is located downstream of the sealing member 24 along the direction of the suction flow. Therefore, the sealing member 24 is located on the path of the suction flow toward the snap-fit ​​part 31, thereby allowing the sealing member 24 to block the suction flow toward the snap-fit ​​part 31.

[0061] Further reference Figure 8 When the second connecting part 21 is fitted onto the first connecting part 12, the sealing member 24 is located downstream of the first snap-fit ​​groove 121 along the direction of the suction flow, while the snap-fit ​​part 31 is located upstream of the sealing member 24 along the direction of the suction flow. Therefore, the sealing member 24 is located on the path of the suction flow toward the snap-fit ​​part 31, thereby allowing the sealing member 24 to block the suction flow toward the snap-fit ​​part 31.

[0062] Further reference Figure 6 In some specific embodiments, the connecting sleeve 3 has an arc-shaped structure and an opening 33. The width of the opening 33 is less than the maximum width of the connecting sleeve 3. Specifically, the connecting sleeve 3 can be approximately a ring-shaped structure with a notch. The connecting sleeve 3 has a certain degree of elasticity. When the connecting sleeve 3 is installed, the overlapping positions of the first connecting part 12 and the second connecting part 21 are inserted into the connecting sleeve 3 through the opening 33. During the installation process, the connecting sleeve 3 can be stretched by the first connecting part 12 and the second connecting part 21 to undergo elastic deformation. After the connecting sleeve 3 is installed in place, the connecting sleeve 3 returns to its original position to engage with the first connecting part 12 and the second connecting part 21 respectively. The width of the corresponding position of the connecting sleeve 3 can be the distance between the relative positions of the connecting sleeve 3 in a first direction, which is perpendicular to the installation direction of the connecting sleeve 3. When the first connecting part 12 is fitted onto the second connecting part 21, the maximum width of the connecting sleeve 3 is the same as or approximately the same as the outer diameter of the corresponding position of the first connecting part 12; when the second connecting part 21 is fitted onto the first connecting part 12, the maximum width of the connecting sleeve 3 is the same as or approximately the same as the outer diameter of the corresponding position of the second connecting part 21. In this embodiment, specifically, the first connecting part 12 can be fitted onto the second connecting part 21.

[0063] Further reference Figures 2 to 6The snap-fit ​​portion 31 of the connecting sleeve 3 can extend from the inner wall of the connecting sleeve 3 toward the center of the connecting sleeve 3. To allow the snap-fit ​​portion 31 to snap into the first connecting portion 12 and the second connecting portion 21, the first connecting portion 12 can be provided with a first snap-fit ​​groove 121 adapted to the snap-fit ​​portion 31, and the second connecting portion 21 can be provided with a second snap-fit ​​groove 211 adapted to the snap-fit ​​portion 31. The first snap-fit ​​groove 121 can overlap and communicate with the second snap-fit ​​groove 211, and the snap-fit ​​portion 31 can be placed within the communicating first snap-fit ​​groove 121 and second snap-fit ​​groove 211 to achieve snap-fit ​​between the snap-fit ​​portion 31 and the first connecting portion 12 and the second connecting portion 21.

[0064] Further reference Figures 2 to 8 In some specific embodiments, when the first connecting part 12 is sleeved on the second connecting part 21, the second engaging groove 211 can be an annular groove, and the thickness of the second engaging groove 211 is adapted to the thickness of the engaging part 31. The wall forming the second engaging groove 211 can abut against the engaging part 31 to restrict the movement of the engaging part 31 and the second engaging groove 211 along the direction of the suction material movement. By setting the second engaging groove 211 as an annular groove, the engaging part 31 can slide within the second engaging groove 211, so that the second connecting part 21 can rotate relative to the engaging part 31.

[0065] The first engaging groove 121 can be a through groove, and the width of the first engaging groove 121 can be adapted to the width of the engaging part 31, and the thickness of the first engaging groove 121 can be adapted to the width of the engaging part 31. When the engaging part 31 is engaged in the first engaging groove 121, the wall forming the first engaging groove 121 will restrict the movement between the engaging part 31 and the first connecting part 12 along the direction of the suctioned material, and will also restrict the rotation between the engaging part 31 and the first connecting part 12. The thickness direction of the engaging part 31 is parallel to the direction of the suctioned material's movement.

[0066] When the second connecting part 21 is fitted onto the first connecting part 12, the first engaging groove 121 can be an annular groove, and the thickness of the first engaging groove 121 is adapted to the thickness of the engaging part 31. The wall forming the first engaging groove 121 can abut against the engaging part 31 to restrict the movement of the engaging part 31 and the first engaging groove 121 along the direction of the suction material movement. By setting the first engaging groove 121 as an annular groove, the engaging part 31 can slide within the first engaging groove 121, allowing the first connecting part 12 to rotate relative to the engaging part 31.

[0067] The second engaging groove 211 can be a through groove, and the width of the second engaging groove 211 can be adapted to the width of the engaging part 31, and the thickness of the second engaging groove 211 can be the same as the width and thickness of the engaging part 31. When the engaging part 31 is engaged in the second engaging groove 211, the wall forming the second engaging groove 211 will restrict the movement between the engaging part 31 and the second connecting part 21 along the direction of the suction material movement, and will also restrict the rotation between the engaging part 31 and the second connecting part 21.

[0068] By configuring one of the first snap-fit ​​groove 121 and the second snap-fit ​​groove 211 as an annular groove and the other as a through groove, when the snap-fit ​​part 31 is connected to the first connecting part 12 and the second connecting part 21, it can remain relatively fixed to one of the first connecting part 12 and the second connecting part 21, while allowing the other to rotate. Therefore, after the flexible connecting tube 2 is connected to the floor brush assembly 1, the flexible connecting tube 2 can rotate relative to the floor brush assembly 1. If the flexible connecting tube 2 and the floor brush assembly 1 cannot rotate relative to each other, the floor brush assembly 1 will rotate relative to the flexible connecting tube 2 when connected to other components due to its threaded connection structure. In this case, the flexible connecting tube 2 will be subjected to shear stress and may be damaged. In this application, by configuring the flexible connecting tube 2 to rotate relative to the floor brush assembly 1, the flexible connecting tube 2 can relieve the shear stress it needs to bear by rotating, reducing the risk of damage to the flexible connecting tube 2 and improving its service life.

[0069] Further reference Figure 6 In some specific embodiments, the snap-fit ​​portion 31 of the connecting sleeve 3 may be provided with a guide slope 311. The guide slope 311 may be provided at one end of the snap-fit ​​portion 31 facing the third connecting portion 22 of the flexible connecting tube 2.

[0070] When the first connecting part 12 is fitted onto the second connecting part 21, and the flexible connecting tube 2 is inserted into the first connecting part 12 of the floor brush assembly 1, the flexible connecting tube 2 will abut against the guide slope 311. The force exerted during the installation of the flexible connecting tube 2 will be transmitted to the guide slope. The locking part 31 will deform outward due to the guidance of the guide slope 311. At this time, the locking part 31 abuts against the outer wall of the flexible connecting tube 2 and the locking part 31 tends to reset due to elastic potential energy. When the second locking groove 211 of the flexible connecting tube 2 moves to overlap with the locking part 31 and the first locking groove 121, the locking part 31 will reset and lock into the second locking groove 211 to achieve locking with the flexible connecting tube 2.

[0071] When installing the flexible connecting pipe 2, the connecting sleeve 3 can first be fitted onto the first connecting part 12 and snapped into the first snap-fit ​​groove 121. Then, when the flexible connecting pipe 2 is installed into the first connecting part 12 of the floor brush assembly 1, the flexible connecting pipe 2 will be driven by the guide slope 311 to expand the snap-fit ​​part 31 outward. After the flexible connecting pipe 2 is installed in place, the snap-fit ​​part 31 will snap into the second snap-fit ​​groove 211 to realize the connection between the flexible connecting pipe 2 and the floor brush assembly 1. Therefore, the flexible connecting pipe 2 only needs to be installed with an installation force in one direction to make the snap-fit ​​part 31 automatically expand outward and automatically snap into the snap-fit ​​part 31 after the flexible connecting pipe 2 is installed in place, making the operation simple and convenient.

[0072] When the second connecting part 21 is sleeved on the first connecting part 12, the connecting sleeve 3 can first be sleeved on the second connecting part 21 and snapped into the second snap-fit ​​groove 211. When the flexible connecting tube 2 is installed into the first connecting part 12 of the floor brush assembly 1, the first connecting part 12 of the floor brush assembly 1 abuts against the guide slope 311 and will drive the snap-fit ​​part 31 to expand outward through the guide slope 311. When the flexible connecting tube 2 is installed in place, the snap-fit ​​part 31 coincides with the first snap-fit ​​groove 121, and the snap-fit ​​part 31 will snap into the first snap-fit ​​groove 121 to realize the connection between the flexible connecting tube 2 and the floor brush assembly 1.

[0073] In a preferred embodiment, the first connecting part 12 is sleeved on the second connecting part 21, and the connecting sleeve 3 is pre-fitted to the first connecting part 12 of the floor brush assembly 1. When the flexible connecting tube 2 is installed, it abuts against the guide slope 311 to deform the snap-fit ​​part 31, and snaps into the snap-fit ​​part 31 after the flexible connecting tube 2 is installed in place.

[0074] Further reference Figures 2 to 4 The triggering unit 32 of the connecting sleeve 3 may include an operating part 321 and an abutting part 322. The operating part 321 is used to withstand external pressure and is located in the middle of the connecting sleeve 3, and can be arranged opposite to the opening 33. The width of the connecting sleeve 3 corresponding to the abutting part 322 is less than the maximum width of the first connecting part 12, and the abutting part 322 and the snap-fit ​​part 31 of the connecting sleeve 3 are located on opposite sides of the maximum width of the connecting sleeve 3, and the abutting part 322 and the operating part 321 of the connecting sleeve 3 can be located on the same side of the maximum width of the connecting sleeve 3. The abutting part 322 of the connecting sleeve 3 is used to abut against the outer connecting part of the first connecting part 12 and the second connecting part 21. For example, when the first connecting part 12 is fitted onto the second connecting part 21, the abutting part 322 is used to abut against the first connecting part 12; when the second connecting part 21 is fitted onto the first connecting part 12, the abutting part 322 is used to abut against the second connecting part 21.

[0075] When the engaging part 31 engages with the first connecting part 12 and the second connecting part 21, a spacer cavity 3211 is provided between the operating part 321 and the outer connecting parts of the first connecting part 12 and the second connecting part 21. Specifically, when the first connecting part 12 is fitted onto the second connecting part 21, a spacer cavity 3211 is provided between the operating part 321 and the first connecting part 12; when the second connecting part 21 is fitted onto the first connecting part 12, a spacer cavity 3211 is provided between the operating part 321 and the second connecting part 21. In this embodiment, the spacer cavity 3211 is specifically provided between the operating part 321 and the first connecting part 12 for explanation. When the operating part 321 is pressed, the operating part 321 can move toward the spacer cavity 3211 to reduce the distance between the operating part 321 and the second connecting part 21. When the operating part 321 moves, the abutment part 322 moves along with the operating part 321, and the abutment part 322 gradually moves towards the wider position of the second connecting part 21. The abutment part 322 is squeezed outward by the first connecting part 12 and expands outward simultaneously, and the locking part 31 expands outward at the same time until the locking part 31 disengages from the second locking groove 211, so that the locking part 31 moves outward to release the restriction on the second connecting part 21. At this time, the flexible connecting tube 2 can be separated from the floor brush assembly 1.

[0076] In some specific embodiments, a pair of snap-fit ​​portions 31 may be provided, with the pair of snap-fit ​​portions 31 arranged opposite each other and respectively used to snap onto the first connecting portion 12 and the second connecting portion 21. For example, the first connecting portion 12 is provided with a pair of first snap-fit ​​grooves 121, and the second connecting portion 21 is provided with a pair of second snap-fit ​​grooves 211. Each first snap-fit ​​groove 121 communicates with the corresponding second snap-fit ​​groove 211 and cooperates with the corresponding snap-fit ​​portion 31. A pair of abutment portions 322 may also be provided, with the pair of abutment portions 322 arranged opposite each other. The snap-fit ​​portions 31 may be located at the free end of the connecting sleeve 3, and the pair of snap-fit ​​portions 31 are symmetrically arranged along the central axis H of the connecting sleeve 3. The pair of abutment portions 322 are symmetrically arranged along the central axis H of the connecting sleeve 3.

[0077] Further reference Figures 2 to 4To facilitate pressing the operating part 321, the operating part 321 can be exposed outside the floor brush housing 14 of the floor brush assembly 1. The user can apply pressure to the operating part 321 from the outside, causing the locking part 31 to release its restriction on the first connecting part 12 and the second connecting part 21. In a preferred embodiment, the floor brush assembly 1 is provided with a receiving groove 13 that penetrates the floor brush housing 14 to communicate with the outside. The receiving groove 13 can be located at the rear of the floor brush assembly 1 and in front of the rear wheel assembly 15. The operating part 321 is installed in the receiving groove 13, and the portion of the operating part 321 exposed to the outside is located at the rear of the floor brush assembly 1 and in front of the rear wheel assembly 15. Adjusting the position of the operating part 321 prevents it from being located in a position prone to accidental operation and prevents it from colliding with external objects and being pressed down when the ground is uneven. In this embodiment, by setting the exposed part of the operating part 321 to the rear side of the floor brush assembly 1 and in front of the rear wheel assembly 15, the risk of user misoperation and being pressed by collision with external objects when the ground is uneven can be reduced.

[0078] In some specific embodiments, to ensure that the operating part 321 can automatically reset after the pressure is released, an elastic element 323 may be provided in the spacer cavity 3211. When the operating part 321 is not pressed, the elastic element 323 abuts against the operating part 321 and may be in an uncompressed state or a slightly compressed state. Preferably, the elastic element 323 is in a slightly compressed state so that the elastic element 323 maintains a force on the operating part 321, causing the operating part 321 to tend to move away from the second connecting part 21. At this time, the locking part 31 of the operating part 321 will have a contraction tendency to ensure the connection stability between the locking part 31 and the first connecting part 12 and the second connecting part 21. When the operating part 321 is pressed and moved, the operating part 321 will squeeze the elastic element 323 to cause the elastic element 323 to elastically deform. When the pressure on the operating part 321 is released, the elastic element 323 rebounds under the drive of elastic potential energy, which will drive the operating part 321 to reset.

[0079] When it is necessary to disassemble flexible connecting pipe 2, refer to... Figure 3 Pressing the operating part 321 causes it to compress the elastic element 323, and the locking part 31 deforms and expands outward to release the restriction between the first connecting part 12 and the second connecting part 21. At this time, the flexible connecting tube 2 can be separated from the floor brush assembly 1. After the flexible connecting tube 2 is separated from the floor brush assembly 1, the pressure on the operating part 321 can be released, and the elastic element 323 drives the operating part 321 to rebound. The locking part 31 resets through the elastic rebound of the connecting sleeve 3 itself to lock into the first locking groove 121 of the first connecting part 12. When it is necessary to reinstall the flexible connecting tube 2, the flexible connecting tube 2 is driven by the guide slope 311 of the locking part 31 to deform and expand outward. After the flexible connecting tube 2 is installed in place, refer to Figure 2The snap-fit ​​part 31 is reset and snapped into the second snap-fit ​​groove 211 of the flexible connecting tube 2 to complete the connection between the flexible connecting tube 2 and the floor brush assembly 1.

[0080] To facilitate the installation of the elastic element 323, the operating part 321 is provided with a mounting groove 3212; when the first connecting part 12 is fitted onto the second connecting part 21, the first connecting part 12 is provided with a protrusion 122; when the second connecting part 21 is fitted onto the first connecting part 12, the second connecting part 21 is provided with a protrusion 122. Specifically, the first connecting part 12 is fitted onto the second connecting part 21, and the first connecting part 12 is provided with a protrusion 122. One end of the elastic element 323 is received in the mounting groove 3212 and abuts against the operating part 321, and the other end of the elastic element 323 is fitted onto the protrusion 122 and abuts against the first connecting part 12.

[0081] In other embodiments, the operating part 321 may not be connected to the elastic element 323. The operating part 321 may adopt an elastic hook structure. When the operating part 321 is pressed, the operating part 321 itself will generate elastic potential energy so that the operating part 321 can spring back to its original position after the external pressure is removed.

[0082] Reference Figure 1 This utility model also provides a vacuum cleaner, which includes a handle module 300 and the aforementioned vacuum cleaner connection module. A connector 301 is provided at one end of the handle module 300 that connects to the vacuum cleaner connection module. The connector 301 is used to engage with the second connecting part 21 of the flexible connecting tube 2 to achieve connection between the handle module 200 and the flexible connecting tube 2. The second connecting part 21 may be provided with an elastic buckle, and the connector 301 may be provided with a snap-fit ​​groove that cooperates with the elastic buckle; alternatively, the second connecting part 21 may be provided with a snap-fit ​​groove, and the connector 301 may be provided with an elastic buckle that cooperates with the elastic buckle. The second connecting part 21 and the connector 301 are engaged through the cooperation of the elastic buckle and the snap-fit ​​groove. Multiple elastic buckles and snap-fit ​​grooves can be provided, and they correspond one-to-one. For example, two elastic buckles and two snap-fit ​​grooves are provided, with two elastic buckles facing each other and two snap-fit ​​grooves facing each other.

[0083] The handle module 300 may include a motor, a dust cup module, and a connecting channel 302 extending from the second connecting portion 21 to the dust cup module. The motor is a common component in existing vacuum cleaners used to generate suction. The dust cup module is used to filter and collect solid matter such as dust and hair from the inhaled material. The connecting channel 302 communicates with the flexible connecting tube 2, so that the suction channel 11 forms a continuous channel. The inhaled material sequentially passes through the suction channel 11 and the connecting channel 202 into the dust cup module for filtration. The solid inhaled material is collected by the dust cup module, while the filtered gas is discharged to the outside.

[0084] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
